Wings of Canon:Blank Sprite

Wings of Canon: Blank Sprite is a multi-chapter story written nearly entirely by SergioTurbo, with exactly one scene provided by Aelit instead. While technically set up as a Protectors of the Plot Continuum mission, it doesn't feature actual bad fanfiction as its focus as it is actually a character-driven standalone story.

It acts as the finale of Wings of Canon, providing closure to the storylines and character development of Sergio Turbo and Nikki Cherryflower in the canon PPC timeline. It doesn't have any direct sequels, as Wings of Canon: Second Strike focuses on Sergio and Nikki's daughter Keiko and The World Without Authors is set in an alternate, non PPC canon continuity.

According to SergioTurbo himself, Blank Sprite's planning started roughly two years before the first chapter was written, with the working title of "Wings of Canon: The Movie" due to it being planned as longer than a regular PPC mission (in fact, before the release of So Much For Sublety, Blank Sprite was longer than the entirety of Wings of Canon). The first chapter was released in December 2013, and the fifteenth and final one was released more than four years later in March 2018.

Mission Record 01 - An easy mission
Sergio, Nikki and Corolla are sent in Cardcaptor Sakura to deal with yet another bad fanifction causing damage to canon, only for their mission to be derailed by Sakura Kinomoto suddenly being missing without it being in the fanfiction's plot. They attempt a search, which proved to be futile, and Sergio goes on to report the situation to the Sunflower Official as a "Blank Sprite": the complete disappearance of a canon character from their universe. The Sunflower reveals that the same thing just happened to Madoka Kaname from Puella Magi Madoka Magica, and the trio is sent to keep surveillance on the house of another possible target: Nanoha Takamachi from Mahou Shoujo Lyrical Nanoha. Their intuition proves to be right, as a quartet of gunmen arrives in a black van to kidnap her. The three agents manage to dispatch them, and sicover that they are Defectives from a Mary Sue Factory, and that the van they were using comes from the Alarm für Cobra 11 universe. The trio picks up the two surviving Defectives and reports to the Sunflower official again, who tasks Sergio and Nikki to get to that universe to try to locate the Factory while Corolla is to provide mission control.

Mission Record 02 - Special Delivery
Sergio and Nikki arrive in the Alarm für Cobra 11 universe, and pretend to be Interpol investigators to get the help of the policemen from the series to get informations about the owner of the van. It is apparently a shipping company going by the name "Bestest Shipping Co.", which is quickly assumed to be a front for a Mary Sue Factory. The company has a contained due to be loaded that very same day, and so the duo commandeers Semir Gerkhan's BMW 3-series to head to the docks as their portal generator seems to be malfunctioning. There, they open the container, finding Madoka Kaname who seems to be aware of their identities as PPC agents. She is also apparently from after she became the Law of Cycles, somehow having been forced back into human form. As they drive off, black Porsche Cayennes try to give chase, but between Sergio's driving and Nikki spellcasting they manage to lose them.

Mission Record 03 – Square Zero
While Sergio keeps driving, Corolla contascts them to inform them that the Defectives they captured weren't failed attempts at making artifial Suvians like the others, but instead were deliberately made as disposable mooks. Interrogation also proved futile, as they were completely unable to speak. Madoka reveals that something is blocking her from performing any kind of offensive magic, but can still heal herself. Nikki attempts to scan her, but the only result is to send magical sparks flying everywhere in the car. Sergio hypothesizes that such a kind of block, and the fact Madoka was being smuggled in a shipping container, might be the work of a trafficking ring planning on sellign canon characters to the highest bidder. Another Cayenne tracks them down, but this time the two agents aren't able to lose them: the Defectives open fire on the BMW, forcing Nikki to focus on shielding spells, and more Cayennes join the chase corralling the BMW on the highway. The BWM is pushed into the jersey barriers multiple times until it is overturned, and once it rolls to a stop the Defectives take advantage of the Agent being concussed to take Madoka back. Sergio attempts to shoot them, but is unable to aim straight due to havign broken a rib in the crash, while Nikki is prevented from joining the fight due to her side's door being jammed shut. The Defectives drive away, and Nikki does her best to heal Sergio's rib at least partially. They decide to head to Bestest Shipping Co.'s headquarters, and as soon as they arrive they hear gunfire from inside. Sergio and Nikki, fearing Madoka and Sakura had managed to break free and the Defectives were trying to gun them down, storm the building. As they fight through several defectives, Sergio seems to slip into a more soldier-like attitude, which worries both Nikki and Corolla. Nevertheless, they manage to take down the opposition and end up meeting Homura Akemi, also from Puella Magi Madoka Magica, who was there looking for her friend. Someone had managed to slip her a note telling her what happened to Madoka and suggesting her to get the PPC's help, and Sergio's in particular. This puzzles the agents, as the organization they work with is supposed to be a secret one. Nikki notices that whoever wrote the message spoke Japanese fluently, but had difficulties writing using the Japanese alphabet. She later also notices that the note has two Italian words written on the other side, "metti tutto", and she slips into speaking that language as she points out that those two words don't make any sense on their own. This causes more puzzlement, as even Nikki herself wasn't aware that she was able to speak Italian. Sergio realizes that whoever wrote it inteded to weite "metticela tutta" instead, which means "give it all". He seems to know who could have written it, but dismisses it as not being possible without saying who. They receive a notice from the Neuss police that they found the Cayenne on which Madoka was taken away, and head there.

Mission Record 04 – I didn’t want you to know that
The car is parked near a warehouse, but as the two agents and Homura enter it they realize it is only a farmer's vehicle shed. They try to search for secret passages, but none are found and are instead ambushed by more Defectives from outside. As they fend them off, the trio receives help from a sniper, and once the Defectives are dealt with the trio attempts to track down the sniper. The sniper is nowhere to be seen, but they find the place they used as a sniper's nest, a spent rifle casing still laying there. As he inspects it, Sergio ends up shocked by the fact that the way the casing is dented marks it as having been shot by a rifle owned by the same person who wrote the note: a former partner of Sergio, Ami Tanegashima, who had died four years earlier. As he wonders what is going on in exasperation, Homura storms off an tries to interrogate one of the wounded Defectives, who ends up dying as she slams it repeatedly on the side of one of the Cayenne's. Sergio and Nikki try to get her to calm down, and she angrily snaps back at them before breaking down in tears. Sergio manages to calm her down with a hug, and Nikki asks him to share his past with them, as it might be related to the incident, to which Sergio agrees.

Mission Record 05 – A burden made of words
Sergio Nikki and Homura head to a cafè to get something warm and recollect their thoughts, where Sergio finally admits the truth about himself: he is actually a reformed Suvian coming from a long, badly written fanfiction called Mai Dire Fine, in which he was a genetically engineered boy who had escaped from his creator, ending up working as an implausibly young Interpol Special Investigator. As the story was a massive crossover, he ended up workign alongside characters from series like Detective Conan and Cardcaptor Sakura, ultimately ending up in a relationship with Sakura Kinomoto despite the fact she's canonically soulmate with Syaoran Li. This is ultimately the reason why she had rejected Nikki, herself a Sakura copy, a few days earlier (Lasting Damage): he is afraid his nature as a Suvian caused another "Sakura" to fall in love with him. Nikki objects, claiming she likes him for what he is now, and that he isn't a Suvian anymore. Sergio continues telling his backstory, revealig how in Mai Dire Fine they were supposed to defeat the Organization from Detective Conan but, since the story was abanoned before they could, it turned out into an all-out World War with him being the only survivor of his group, something which led him to develop a "shoot first, ask questions later" attitude during PPC missions. Having realized his nature as a Suvian due to a near miss encounter with PPC agents, Sergio had spent some time hunting other Suvians on his own, vigilante-style, before ending up in a private military company, Strike Dove Incorporated. It is there that he meets and befriends Ami Tanegashima, though another teammate of theirs, Vera Heartbound, eventually reveals herself as a Suvian. As she felt upstaged by Sergio, during a mission in which Sergio and Ami were deployed alone she organized an ambush, with Ami getting killed in it. As soon as Sergio discovered the truth about the assignment, he confronted Vera and ended up mortally wounding her in combat, after which he fled Strike Dove and ended up beign recruited into the PPC by the two agents who had been sent in to take Vera out, and from which Sergio had unwittingly stolen the kill. As Sergio's recollection is over, they make an effort to try to understand if there's a relation between the current happenings and Sergio's past, without much success. Corolla, who had been following the conversation through a holographic window, managed to discover that the following day's evening there's an oddly set-up anime merchandize auction set as a formal gala dinner, with apparently some "special, one of a kind" merchandize being offered. The group decides to investigate it.

Mission Record 06 - Echoes
Sergio, Nikki and Homura decide to call it a day and rent an hotel room to get some sleep. Nikki ends up having a dream in which she's Sakura and, alongside Sergio and some of the Mai Dire Fine characters, she's fighting some kind of giant robotic spider. Upon waking up, she tells the dream to Corolla, asking her opinion about it as it felt like she was in Sergio's story. In the meanwhile, Sergio is having a much nastier nightmare: he keeps running into the dead bodies of his friends and family, and is then confronted by a personification of his guilt taking the appearance of Sakura Kinomoto in shackles. Upon waking up, he realizes Nikki is looking outside the window, lost in thought. As she's wearing only her nightgown, Sergio puts his jacket over her shoulders, and they end up having an heartfelt talk about the Blackout's revelation that they might die soon. Nikki, feeling reassured, ends up falling asleep while sitting with her head on Sergio's shoulder, with Sergio musing that something like that had already happened in Mai Dire Fine, and wondering if he's making with Nikki the same mistake he did with Sakura six years earlier. In the meanwhile, Corolla discovers that Nikki's dream was, somewhow, a perfect recollection of a scene from Mai Dire Fine, despite the fact Sergio didn't mention that particular incident in his recollection. She decides to sleep on it, but she accidentlly stumbles in some of Sergio and Nikki's belongings and makes the discovery that an hairpin Nikki since before she joined the PPC is the very same Sakura was wearing in a photo taken during Mai Dire Fine, implying the two might be one and the same.

Mission Record 07 – Mr. Turbo, I expect you to dine
Corolla manages to get invites for "Guido Piano" and "Tsubasa Ohka", the two false identities Sergio and Nikki use to infiltrate the gala event while Homura sneaks into the basement to try to locate Madoka and Sakura. Some time into the event, the host makes a speech, and to Sergio's horror is none other than Vera Heartbound, who actually survived her fight against him. Vera greets him right away, mocking him before siccing her Defectives on the two agents. As she retreats, she is intercepted by Homura, who is however unable to land a single hit on her and ends up getting seriously injured. Sergio and Nikki defeat the Defectives and hurry to Homura's aid. While at first the sight of the injuured Homura causes Sergio to have a flashback of Ami's death, together with Nikki they manage to heal Homura's injuries before it is too late. They reason out that Vera is not after Madoka and Sakura, but they were the bait to draw in the real target: Sergio, as Vera likely wants revenge. As the portals started working again, they retreat to the PPC's headquarters and report to the Sunflower Official. The Sunflower is appalled at the turn of events, and tries to get the case off their hands, but Sergio hands in his neuralyzer and flash patch to resign, reasoning it out that, since Vera is after him and not after the PPC or the canon characters, the case is personally his. The Sunflower begrudgingly allows it, but gives him only three days to solve the case before he will send another team in. Sergio suspect that Vera is using as a base of operations the place he and Ami were ambushed at the day the latter died, so the group heads there. He also reveals that the place used to be an Organization laboratory during the late days of the war against them, and that he lost the last of his original group there. As Vea seems to have spent four years planning her revenge, Sergio suspects she might have chosen as her base the place where he took two heavy losses. As they portal there, Corolla takes a brief detour to Mai Dire Fine, witnessing one scene in which Sakura is worrying about Sergio having been injured while rescuing her. The way the girl acts doesn't match the way Sakura is supposed to act, but is a perfect match to Nikki. Corolla runs a CAD scan on her, and her suspicion is confirmed: that girl in indeed not the canonical Sakura, but Nikki.

Mission Record 08 – Lingering Ghosts
The laboratory is deep into the snow-covered Alaskan wilderness, so the quartet rents a tracked pick-up truck to get there. On the way, the run into the wreck of one of the helicopters that Sergio and his group from Mai Dire Fine had used to try to make a last assault - one helicopter was shot down en-route, and the remains of at least some of the occupants are still inside. They take a note to arrange for a proper burial, and continue towards the laboratory. As they reach it, the place looks clear, and inside the only trouble awaiting them is Sergio being victim to another flashback. The place turns out to not be Vera's base after all, theit only noteworthy find is AMS-02 Mjolnir, the magical weapon of one of Sergio's old friends, Carol Liddell. The group plans on heading back, but a heavy snowstorm has started making it impossible and so they decide to spend the night there. Before they fall asleep, Corolla attempts to tell Sergio her findings about Nikki by hinting at the possibility the Sakura from Mai Dire Fine was actually a Character Replacement and might still be around. Sergio flathly rebuts that if she was, she would've been dead as she was abouard the crashed helicpter, and ends the conversation there.

Mission Record 09 – Buried Regrets
Durng the night, Sergio has a dream in which he relives the aftermath of the old battle at the lab: the time machine they were looking for didn't exist. It was just an ambush by the organization, and he was the only survivor. He faked his death and planned to bomb the Organization's victory celebration, stopping on the way only to say goodbye to his aunt Virgilia as he doesn't plan on making it out alive. Despite her protests, he carried out the plan. Sergio wakes up, musing on the fact that someone had other plans for him as the explosion ended up throwing him into a plothole instead, allowing him to survive. He gets up to clear his head for a walk, and finds that like him Homura is having trouble sleeping. He correctly deduces that, since she had been though hell like him, she also suffers from recurring nightmares. He is unable to give Homura a proper answer on how he is dealing with his past, and he admits that he's actually still running away from it. He also muses that he's not sure whether he is human or just a weapon, but that at least he "can make sure [he is] aimed in the right direction" since he was indeed created as a weapon.

Mission Record 10 – Broken Mirrors
In the meanwhile, Nikki has a dream in which she is facing Carol in a fight, the dream ending just as she is defeated. As she wakes up, she is puzzled - she was once again in Sakura's shoes, and Carol was supposed to be her ally. Corolla wakes up as well, and seems suprisingly nowledgeable on how her dream played out. Corolla also sets up Mjolnir in its combat form, which further surprises Nikki as it looks exactly like it did in her dream. Corolla then proceeds to play a recording from the weapon, which plays exactly as Nikki'd dream did. Corolla then proceeds to show her another snippet from the same story, the one she recorded on her short portal trip, showing the Sakura from Mai Dire Fine acting towards Sergio in a way that would not be canonical for her, but fitting perfectly with Nikki's personality. With a bit of pushing from Corolla, Nikki comes to the realization that she is, in fact, the Sakura from Mai Dire Fine - having somehow survived the crash, but having lost a few years of memories. Corolla resumes Carol's recording, and towards the end Sergio's sister Kathleen asks for a recording as Sergio takes "Sakura", or rather Nikki, aside. It turns to be the moment he confessed his feelings to her, and Nikki can barely control her embarassment as Corolla cheers them on as they share their first kiss. The recording ends with Kathleen saying that they "did it", to which Corolla remarks that it is not quite ture, but she will "continue battle for [her]". The following morning, Nikki attempts to tell Sergio of her actual identity as they head out, but she is cut off by an explosion. The roof of the corridor caves is, and she and Corolla ends up getting separated from Sergio and Homura. As they make radio contact, Sergio remarks that he got a problem due to "stuff not staying dead". Just as Nikki tries to ask him what's goign on, she and Corolla get greeted by a girl looking like Nikki's splitting image: Kurara Tsukimoto, an evil clone of her created by the Organization. She correctly deduces that Homura and Sergio are facing the latter's clone, Sergej Speed, and tries to talk Kurara down but is unsuccessful: Kurara is now a contract assassin, and she's been apparently paid to kill them, and as a clone she will only be free of the originals' shadow when she kills both Nikki and Sakura. Armed with a submachine gun and a bladed yo-yo, Kurara managed to get an early advantage by pulling Nikki's Device, Vanguard, off her hands, but Corolla manages to unlock Mjolnir for Nikki to use for a counterattack. Nikki managed to get Vanguard back, and eventually overpowers Kurara, killing her off for good.

Mission Record 11 – Lost Lightning
Like Nikki did, Sergio attempts to talk Sergej down, but is also unsuccessful. While he's aware of his nature as a clone, Sergej is still resentful towards Sergio: their creator, Marcus, only had ever seen Sergio as a son of sorts, while Sergej was only the weapon to take him down when Sergio rebelled despite Sergej being closer to what marcus wanter from his "original". Sergio rebutts that he was also made as a weapon, and that Sergej is free to take the title of Marcus' son from him, but it does little to stop him: Sergej attacks with his rifle and rifle-mounted grenade laucher. After a tough fight, during which Homura gets seriously injured again (but manages to heal due to the abilities she has as a Puella Magi), Sergio manages to take out Sergej by stabbing him in the heart with his combat knife. The clone smanages to weakly state that the two of them are "still the same after all" before dying. Nikki and Corolla, havign dealt with Kurara, arrive in the same room. They scold both Sergio and Homura for defining themselves as not human, and reveal that Kurara let out a small bit of useful information: Sakura might be held in Venice. As they head out, the quartet runs into one of Strike Dove's squads: Striker Team Raptor, among their best and on firendly terms with Sergio. They reveal that Sergio had been considered MIA since the old base collapsed, and that they were on the trail of the clones when they caught the signal from Sergio's CODEC. The quartet gets a lift to Strike Dove's rebuilt base, as Sergio intends to talk to Strike Dove's founder and commander, Colonel Johnson. The latter welcomes him back warmly, and provides him with evidence showing that Vera had ordered the assassination of another former teammate of theris as well, one that at the time was filed off as a drive-by shooting by gang members at the time. As Vera is deemed out of control, Johnson officially tasks Sergio and his team to take her down, alongsie telling them to get at least a meal and a shower before heading out. Nikki, after taking up the offer for a shower, ends up meeting a short, black-haired girl who asks her if she can deliver a book to Sergio, one the girl has apparently borrowed years earlier. Nikki is puzzled, since the girl looks in her mid-teens at most, but agrees. The girl accompanies her towards Sergio's room, and gives her a somewhat cryptic message to give to Sergio before disappearing. As Nikki delivers the book and describes the girl to Sergio, he goes into shock as the girl is apparently the ghost of Ami Tanegashima. He runs to her room, which is now empty much to Nikki's confusion - when the girl took the book out of her room, it had a full set of furniture in it. They keep discussing the matter as they head towards the mess hall for lunch, but as they sit down to eat the base's alarm blares.

Mission Record 12 – Guardian Angel
Four years earlier, Ami runs to Johnson's office, late for her team's introduction to their new teammate. The new teammate is Sergio, who has just joined Strike Dove. Later, Ami runs into him on the shooting range, and gives him some suggestions on how to improve his aim. Those tips work, and their chat about their guns ends up prompting Ami to reveal that her rifle used to be her father's, and both of her parents had died fighting the Organization. To her surprise, at her mention of her own age being too young for fightign but wanting to continue her parents' battle anyway, Sergio reveals to be younger than she expected, being sixteen at the time, and he admits he has fought in a "resistance" against the Organization. Sergio's experience turns out to be vital to their team, Striker Team Raven, as the leader, Vera, doesn't seem to have any grasp of tactics. Sergio manages to get the team out of trouble more than once, which ends up annoyin Vera dut to him stealing the scene from her. Over time, Ami and Sergio end up bonding over their shared love of some anime series and the Ace Combat series of videogames, with her eventually falling in love with him. On the other hand, Vera can't stand Sergio anymore, the last straw being him winning against her after she challenged him and Raptor Team in an improvised car race on the base's grounds. The tries to get him booted from Raven Team, only for Johnson to point out that without his quick-thinking many of her team's operation would'0ve likely endedu p in failure, and that she has been given remedial classes in tactics. Johnson also temporarily gives the team's command to Sergio, which causes Vera to storm off in anger while statign her intention to leave the team as she doesn't want work under him. This makes Johnson assign the role of team leaderto Sergio permanently, alongside the promotion to Captain. Sergio is initially unwilling to accept, but does so after Ami and their other teammate James convince him. After soem time, Ami asks Sergio out planning to confess her feelings to him, but ends up giving up as he says something suggesting he has a girlfriend. It turns out that Sergio is still traumatized by having "lost" "Sakura" (actually Nikki), and she decides to not confess for the time being as she understands it as him being still mourning a dead girlfriend. An unspecified amount of time after, Ami and Sergio are shocked by the news of James having died in a drive-by shooting, which is believed to have targeted his brother Carl, who had just been released from prison after serving his sentence dut to associating with a criminal gang. Now Sniper Team Skystreaker, Sergio and Ami end up on a ridicolous bad luck streak during their operations: somehow, the enemy can always pinpoint their position and send hunting squads after them. During one of these, Ami wakes up on one of Strike Dove's helicopters after having been shot, and to her surprise she is unable to catch Sergio's attention, or that of the door gunner. She is also not feeling any pain from the injury in her shoulder, and is able to move the arm with no issue, which puzzles her. She then finds a body bag that looks like it is containing the body of someone her height. She tries to open it, but her fingers pass right through it, making her come to the realization that she is now a ghost. A few days afterwards, Ami follows Sergio as he investigates the matter, coming to the realization that it was Vera the one leaking the intel about their operations to get them killed. Sergio loads his rifle and goes to confront Vera, who has no qualms admitting that she indeed wants them dead. Sergio also accuses Vera to be a Suvian, which Vera doesn't deny, being actually proud of being one. They end up fighting each other, with Sergio overpowering her and leaving her for dead as a earthquake starts causing the building to collapse. Sergio comments that Strike Dove was probably brought into existence by Vera, but Ami doesn't believe it to be the case. Sergio then leaves the base, but stops driving shortly afterwards. He now believes that he can only indirectly cause death and suffering anywhere he goes, and puts his pistol at his own head planning to commit suicide. Ami is unable to do anything to stop him, being incorporeal, but before he can pull the trigger his attention is caught by two PPC agents, who end up recruiting him.

Mission Record 13 – Not Alone Anymore
Strike Dove's base is under attack by Defectives, and Sergio, Nikki, Corolla and Homura help Striker Team Raptor repel those as the south gate. The attack turns out to be a diversion, though, as Strike Dove's radio tower gets sabotaged just as the Defectives are repelled. The two teams head there, finding Colonel Johnson there already inspecting the damage. As they discuss the incident and how to deal with it, Vera makes her appearance. She's on top of the tower, and angrily snaps at the people below for ruining her "story", her sanity clearly slipping as she declares they will all die for it. Johnson orders his men to open fire on her, but none manages to hit her as she retreats from the railing. Sergio starts climbing the tower's stairs to chase after her, but before anyone can follow him the flight of stairs below the one he is on is destroyed by an explosive charge. At the same time, another wave of Defectives attack the base, forcing Strike Dove, alongside Nikki, Corolla and Homura, to focus on them instead. Sergio confronts Vera on the tower's upper floor, but the fight quickly turns in Vera's favor after she manages to break his damaged rib again. He is saved by Ami's intervention, her ghost shooting one of Vera's guns out of her hand, but eventually Vera still manages to heavily injure him. Before she can finish him, though, Nikki intervenes, having somehow managed to climb the tower despite the destroyed stairs. As she fights Vera, Sergio passes out, finding himself in some sort of limbo alongside his sister Kathleen, who had died six years earlier. She chastizes Sergio for running away from his past instead of accepting it, pointing out that the deaths of his friends were not his fault. She also hints at Nikki's real identity, causing Sergio to realize she's the "Sakura" from Mai Dire Fine. As he starts to wake up, Kathleen wishes him good luck. In the meanwhile, Nikki is facing Vera in a sword duel, her Device's energy sword mode against Vera's katana. Nikki eventually overpowers her Suvian opponent, her Device cutting through the katana. Nikki then uses her most powerful spell, Raging Blossom, which blast Vera off the tower. Nikki then rushes to Sergio's aid. He is severely injured, and Nikki has barely enough mana left to heal him. He eventually wakes up, and apologizes to Nikki for having made "the girl [he has] always loved cry". Nikki hugs him, realizing that he now knows of her identity, and reiterates her promise to help him carry his burden before pulling him in a kiss.

Mission Record 14 – Wandering Star
Vera is still on the run, and Sergio tells the full story of her nature as a Suvian, and the fictionality of their world to Johnson and Striker Team Raptor. Since Vera's base of operations seems to be in Venice, Johnson finds for Sergio, Nikki, Corolla and Homura some seats on an United States military C-5 Galaxy that is planned to stop in the Malpensa airport in northern Italy. Johnson also assigns Raptor Team's leader, Josh Colt Jr., to follow them as backup. During the flight, Nikki tells what happened to her after the helicopter crash: she had ended up in a plothole and woke up next to the real Sakura, causing a fair deal of confusion for the Cardcaptor Sakura characters until Eriol managed to realize that she is from an alternate world. He was able fing a way to send her back to her world, and she then learned from Virgilia of Sergio's suicidial plan to stop the Organization, but she was too late to stop him. Nikki then met the Eriol from Mai Dire Fine, who pointed her to a plothole predicting that she'll eventually be able to find him if she enters it, but that will "lose herself" before finding him. Nikki took the chance, ending up jumping from world to world as she kept looking for Sergio. She also meet Ami, from whom she received occasional help, but was at that point unaware of her nature as a ghost. The last world Nikki ended up was a fanfiction crossing over with Cardcaptor Sakura, the story's world forcing her into Sakura's place by eraing her memories and de-aging her body. From that world a plothole brings her to the PPC's headquarters, leading to the events of Planes, Guns, Clones and usual PPC stuff. The group decides to try to get some sleep during the flight, with Nikki eventually waking up mid-flight finding Ami at her side. After preventing Nikki from waking up Sergio, Ami proceeds to have a heartfelt talk with her about why she is helping them from beyond the grave: sicne Sergio managed ti brighten her life after she lost her parents, she wanted to ensure he could be happy. Nikki correctly deduces that Ami was in love with him as well, to which Ami doesn't deny it but reassures her that she doesn't want to be seen as her rival - after all, she's already dead, and if there's someone who can keep the "darkness" away from Sergio's life, that's Nikki. Sergio stirs in his sleeps, distractign Nikki, and Ami takes that as a cue to disappear. A few hors later, in the Malpensa airport, Nikki takes a bathroom break only to ambushed by Vera, who manages to narcotize her.

Mission Record 15 – The reason to fight
Sergio realizes Nikki is late, and sends Corolla to check on her. Corolla finds Nikki's Device abandoned on the bathroom floor, but no trace of her, and she report it to Sergio. Immediately afterwards, Vera videocalls him, showing him that she has kidnapped Nikki and giving him a sadistic choice: he can either rescue her, or Madoka and Sakura - as soon as Sergio does one, she will execute the other. This sends Sergio into shock - he can't allow Madoka or Sakura to be killed, as it would be irreparable damage to their universes, but he can't bring himself to sacrifice Nikki for them. Corolla attempts to talk to him, but he doesn't listen and so she proceeds to angrily slap him claiming that finding a solution to this kind of problem should be easy for someone who single-handedly defeated an evil organization that had taken over the world - he should stop dismissing his fame as a hero as undeserved, but instead live up to it. Sergio, realizing he still has the portable disguise generator which is part of his PPC agent kit, gives it to Josh as part of his plan: have two "Sergio" perform both rescues simultaneously. Sergio then proceeds to recover his cars: he lends his Sprinter Trueno to Josh, who will use it to go alongside Corolla and Homura to rescue Madoka and Sakura, and Sergio will use the Stormer, the car he build while he was a Suvian, to chase after Vera as it is fast enough to intercept her before she arrives to Venice. Josh, Corolla and Homura are successful, and Sergio manages to send a CODEC message to Ami asking her to snipe out the radiator on Vera's Porsche Carrera GT while he chases it down. This causes the Porsche's engine to fail, prompting Vera to abandon the car and take shelter in a ruined farmhouse. Sergio fires on her, and manages to injure her before freeing Nikki from the Porsche. Together, they follow Vera's blood trail and manage to take her by surprise, subduing her and charging her for her crimes before executing her. Josh, Corolla, Homaura and Madoka arrive at the scene, having already sent Sakura back to her world. It is revealed that Homura and Madoka had both split off into two individuals: the canon ones, who are already back in their world, and the ones there who have the memroies of the whole incident. Turns out Madoka had actually let herself be kidnapped by Vera to engineer a situation in which Homura would meet Sergio, Nikki and Corolla, as she thought not only that the trio of PPC agents could use her help but their meeting would prevent Homura to do down the self-destructive spiral she was planned to go through the Puella Magi Madoka Magica: The Rebellion Story movie, but a split in the characters was caused instead. The Sunflower Official contacts them, unhappy about the development, to which Sergio replies that the PPC is now out of jurisdiction, backed up by "Madoka" claiming her name is Aya, and her friend is Kuroko, not Homura, so they're not Madoka Magica canon characters. The Sunflower begrudgingly agrees, and both Sergio and Nikki confirm their resignation from the PPC. The following morning, Sergio and Nikki wake up together at Sergio's old house, and start working on plans for their future. In the epilogue, set more than twenty years afterwards, Corolla tells the story of the Blank Sprite Incident to Sergio and Nikki's daughter Keiko, who has just become a PPC agent herself.

Trivia
During planning, the story went through several revisions before its final form. Nikki and the "Sakura" from Mai Dire Fine being the same individual was one such change, as SergioTurbo had originally planned to keep the two characters separate until the latest revision. As such, by his own admission, Nikki's character development arc during Blank Sprite is smaller than Sergio's. As SergioTurbo himself stated, the story's finale went through four different versions, the penultimate one getting fully written before being rejected.

Aelit provided the scene in which Sergio met Kathleen in chapter 13. Kathleen was one of Aelit's characters in Mai Dire Fine, which he hadn't used since Mai Dire Fine was abandoned.

Blank Sprite was intended to be the final story featuring Sergio and Nikki as main characters, as SergioTurbo was not planning The World Without Authors yet and had distanced himself from the PPC by the time Blank Sprite was finished. As such, since Mai Dire Fine had "Sergio" as the first word, SergioTurbo deliberately tweaked the last sentence of Blank Sprite to end with "Nikki", as a nod to Mai Dire Fine, Wings of Canon and Blank Sprite being Sergio and Nikki's saga.
